Structure of Eukaryotic Cells - Essay Example

An essay "Structure of Eukaryotic Cells" discusses the structure of eukaryotic cells and the importance of the membranes. The eukaryotic cells have a great similarity to the prokaryotic cells which contain structures such as ribosomes, plasma membrane, and cytoplasm. …

The eukaryotic cells are made up of numerous rod-shaped chromosomes. They are structured to compose of several membrane-bound organelles such as the mitochondria, Golgi apparatus, chloroplasts and endoplasmic reticulum. These organelles found in the eukaryotic cells have remarkable cellular functions. The eukaryotic cells are well structured and protected by a membrane-bound nucleus. This nucleus that surrounds the membrane is considered as a true nucleus (Lanza, 2009). Additionally, almost all eukaryotic organelles are divided with the rest of the cellular space by a membrane. The eukaryotic organelles are surrounded by a membrane that is based on lipid bilayers which are relatively comparable to the cell's outer membrane, but it is not similar. In summary, the aggregate area of a cell's internal membranes by far-off surpasses that of its plasma membrane. Similarly, organelle membranes just like the plasma membrane role are to retain the interior fluids in and the exterior fluids out. This separation allows several types of biochemical reactions to take place in diverse organelles (Lanza, 2009). Each of the organelles has a particular role in the cell and all of the cell's organelles work collectively in a unified manner to achieve the inclusive essentials of the cell. For instance, in a mitochondria cell's, the biochemical reactions send energy from pyruvate molecules and fatty acids into a molecule rich in energy called adenosine triphosphate (ATP).

e various researches done on evolution of cells by different scientists each research is trying to elaborate himself by really looking in the weakness of the opponent as the weakness from you will be used as the improvement of the other.
However, with criticism many theories

Light Microscope or Electron Microscopes are used to view these tiny cells. These cells are of many different types, which make the appearance and characteristics distinct from each other. Eukaryotic and Prokaryotic cells are two such cells which have DNA as their generic material.

They may also have chloroplasts in the cytoplasm (Bowes, 1996).
Living things are constructed of cells. Living things may be unicellular or multicellular. Cell structure is diverse but all cells share common characteristics (Bowes, 1996). The cell theory states that:

4). Prokaryotic cells are classified as either bacteria or archaea. Another major difference is that eukaryotic cells have most DNA strands contained in a nucleus, whereas prokaryotic cells have circular DNA and do not have a nucleus (Fancher). Eukaryotic cells also have organelles, which are specialized structures that transfer energy that prokaryotic cells do not have (Krough, Ch.

This theory is most efficient in being able to explain the origin of chloroplasts (in this case a photosynthetic prokaryote such as a cyanobacterium would be the endosymbiont) as well as mitochondria (perhaps an aerobic heterotroph). The progenitor of the mitochondria or chloroplast could have gained entry into a host prokaryote as undigested prey or as an internal parasite after which the "arrangement" quickly became mutually beneficial to both partners (the "host" cell and the endosymbiont).

The macromolecular components of the prokaryotic cell are relatively basic compared to their eukaryotic counterparts. Eukaryotic cells in contrast are much more complex and take a longer time to replicate during cellular division. One defining feature of the eukaryotic cell type is the presence of abundant organelles, microscopic structures which serve as partitioned areas of specific activity within a cell (Prokaryotic and Eukaryotic Cells, 2000).

The mechanisms of structuring, energy circulation and reproduction are all based on the formulation of various cells in our bodies. The study of cells is called Cell Biology.
The organic cells are of such a small size that they cannot be viewed

Cells, such as those of skin, hair, and muscle, reproduce by means of mitosis. Mitosis is what happens with a eukaryotic cell is separated from the chromosomes within the cell nucleus and is divided into two identical sets of two daughter nuclei.

1. Organelles. One characteristic of eukaryotic cells is that they contain organelles, which each have a specific structure and function. Use your text, the Assignment 5 image file, and Internet or other resources to complete the table below to show details of the main

Similarly, the nucleoid region in the bacteria also tends to be located towards the center. In plant cells, however, it is located on the side due to the presence of the central vacuole.
The endoplasmic
